Description

Verwendung von Legierungen für Gegenstände, die bei hohen Temperaturen höchste Warmfestigkeit aufweisen müssen Zusatz zutn Patent 730 6,30 Die Erfindung betrifft die Verwendung von Legierungen für Gegenstände, die bei hoher Temperatur hohen mechanischen Beanspruchungen ausgesetzt werden, und stellt eine Weiterentwicklung des Patents 73o 63o dar.Use of alloys for objects that must have the highest heat resistance at high temperatures Addendum to Patent 730 6.30 The invention relates to the use of alloys for objects that are exposed to high mechanical loads at high temperatures, and represents a further development of the patent 73o 63o .

Für die Herstellung von Gegenständen, die bei Temperaturen von 5oo° und darüber, insbesondere oberhalb 6oo° höchste Warmfestigkeit aufweisen müssen, sind schon Legierungen vorgeschlagen worden, die als Grundbestandteile Eisen oder Nickel enthalten, ferner in wechselnden Mengen Chrom, Aluminium, Molybdän, Wolfram, Tantal, Niob, Thorium, Titan, Zirkon. Es wurde nun gefunden, daß für diesen Zweck besonders vorteilhaft Legierungen verwendet werden, ,die hierfür noch nicht vorgeschlagen wordensind und die wie folgt zusammengesetzt sind: mehr als 25%, aber höchstens 4o0;o Chrom, 57 bis i % Eisen, mehr als 3 0lo , aber höchstens i2010 Molvbdän, das, teilweise oder ganz durch Wolfram ersetzt sein kann, o bis i % Mangan, o bis i oto Silicium, o,3 bis 200;o von einem oder mehreren der Metalle Tantal, Niob, Thorium, Titan, Zirkon, Rest Nickel.For the production of objects that can be used at temperatures of 5oo ° and above, especially above 600 °, must have the highest heat resistance, alloys have already been proposed, the basic constituents of which are iron or Contain nickel, also in varying amounts of chromium, aluminum, molybdenum, tungsten, Tantalum, niobium, thorium, titanium, zircon. It has now been found that for this purpose It is particularly advantageous to use alloys that have not yet been proposed for this purpose and which are made up as follows: more than 25%, but at most 4o0; o chromium, 57 to i% iron, more than 3 0lo, but not more than i2010 Molvbden, the, can be partially or completely replaced by tungsten, o to i% manganese, o to i oto Silicon, o, 3 to 200; o of one or more of the metals tantalum, niobium, thorium, Titanium, zirconium, the remainder nickel.

Tantal ist in den Legierungen zweckmäßig bis i50'o, insbesondere in Mengen von 2 bis 80,'o, vorhanden, Niob bis i 5 0,'o, insbesondere 2 bis. 8 0`o, Titan bis i2%, insbesondere 2 bis 8 0'o, Thorium bis 80!0, insbesondere 2 bis 50;'o, Zirkon bis 80;o, insbesondere o,i bis 60'o. Die Legierungen sind dabei im allgemeinen praktisch frei an Kohlenstoff; sie enthalten n;-ecl.:mäßig nicht mehr als 0,040!o Kohlenstoff. Wenn die Legierungen bei Temperaturen bis etwa 700° gebraucht werden sollen, dann werden sie vorteilhaft in kalt gewalztem Zustand verwendet. Sollen sie bei Temperaturen oberhalb etwa 8oo' arbeiten, dann werden sie vorteilhaft in möglichst hoch vorgeglühtem Zustand verwendet, wobei die Glühtemperatur oberhalb der Gebrauchstemperatur liegt. Die Verwendung in hoch vorgeglühtem Zustand empfiehlt sich insbesondere dann, wenn. die Gebrauchstemperatur oberhalb der Rekristallisationstemperatur liegt.Tantalum is useful in alloys up to 150 °, especially in Amounts from 2 to 80, 'o, present, niobium to i 50,' o, in particular 2 to. 8 0`o, Titanium up to 12%, in particular 2 to 8%, thorium up to 80%, in particular 2 to 50%, Zircon to 80; o, in particular o, i to 60'o. The alloys are generally practically free of carbon; they contain n; -ecl .: moderately not more than 0.040! o Carbon. If the alloys at temperatures up to about 700 ° are to be used, then they are advantageously used in the cold-rolled state. If they are to work at temperatures above about 8oo ', then they are advantageous used in the pre-annealed state as high as possible, with the annealing temperature above the usage temperature. We recommend using it in a highly pre-annealed condition especially if. the use temperature above the recrystallization temperature lies.
